Abstract: A vehicle power management system and a power management method thereof are provided. The power management method includes: determining, by a microcontroller, whether or not a voltage of an ignition-off signal is less than a voltage threshold when the microcontroller receives the ignition-off signal; stopping a vehicle power supply from charging a backup battery, and using the vehicle power supply to charge a back-end load; activating a counter of the microcontroller; stopping the vehicle power supply from charging the back-end load, and using the backup battery to charge the back-end load when a counting time of the counter reaches a first time threshold; sending, by the microcontroller, the ignition-off signal to the back-end load when the counting time of the counter reaches a second time threshold; and stopping the backup battery from charging the back-end load when the counting time of the counter reaches a third time threshold.

Abstract: An electronic device with a connector supporting multiple connection standards includes the connector, a first multiplexer circuit, a processor and a controller. The connector includes a detection pin and at least one signal pin. The first multiplexer circuit is coupled to the at least one signal pin. The processor is coupled to the first multiplexer circuit. The controller monitors the detection pin. The first multiplexer circuit electrically connects the at least one signal pin to the controller. Upon detecting a hot-plug signal occurring at the detection pin, the controller issues a confirmation command via the first multiplexer circuit and the at least one signal pin to request a reply of a device signal. Upon receiving the device signal, the controller controls the first multiplexer circuit according to the device signal to electrically connect the at least one signal pin to the processor or the controller.

Abstract: An electronic device includes a case containing a universal serial bus (USB) transmission port, an embedded control unit, a central processing unit, a power supply unit and a multiplex control unit. The multiplex control unit has a first usage mode and a second usage mode. The multiplex control unit is normally in the first usage mode, and switches to the second usage mode when a switch signal is received. In the first usage mode, the multiplex control unit is powered by the power supply unit, and the multiplex control unit builds up a first transmission path between the central control unit and the USB transmission port. In the second usage mode, the multiplex control unit is powered by an external device connected to the USB transmission port, and the multiplex control unit builds up a second transmission path between the embedded control unit and the USB transmission port.

Abstract: A vehicle power supply circuit monitoring system and a vehicle power supply circuit monitoring method are provided. The vehicle power supply circuit monitoring system is adapted to a vehicle power supply and a vehicle load device, and includes a power monitoring circuit and a control circuit. The power monitoring circuit is electrically connected to the vehicle power supply and the control circuit. The power monitoring circuit monitors two different input load powers at two different time points. The control circuit calculates an external power loop equivalent impedance according to the two different input load powers. When the external power loop equivalent impedance is greater than a designed impedance threshold, the control circuit executes a warning procedure.
